My Nextjs development server is crashing every time I try to update my next.config.mjs file (error and code below). I'm trying to update my config to allow an external image source, but the issue doesn't seem to be related. The crash happens regardless of if the images property is in my config.

If I update the file while the development server isn't running and then start the server, the new config doesn't appear to be recognized until I save the config file again. At that point the server will crash after a second or two.

I've tried deleting node_modules and reinstalling on node 20.4.0, 18.17.0, and 16.17.0 and the error persists.


Error:

node:events:490
      throw er; // Unhandled 'error' event
      ^

The trace file mentioned in the error is never actually created...
